The horizontal flange issecured to the underface of the roof sheet by a weld 20 in the anglebetween its end and the body of the sheet. The

edges of the ridge panels of adjacent sheets are preferably not flangedrbut are spaced somewhat apart and the top edge of the free side of thecarline member lies below the margins of adjacent sheets and spans thegap between their edges, and the sheets and carline members are allwelded together by the single weld I1 which illls said gap.

In the construction illustrated in Fig. 1, the carline members extendfrom side plate to side plate and have their ends resting on and weldedto the inturned legs of the side plate, and the running board 2i is madeby merely painting and sanding the longitudinal ridge panel 8. In theconstruction illustrated in Fig. 8'however, the carline members |6aterminate considerably short of the side plates and are welded directlyto the roof sheets; and the running board comprises a metal sheet Ilawelded to in direct surface contact with the longitudinal ridge panel ofthe roof with its side margins extending beyond the inner ends of thechannel panels Il so as to furnish grips for the trainmen.

The present roof has several advantages. Its flat longitudinal ridgepanel is well adapted to support a running board without substantiallyincreasing the thickness of the roof and it is adapted to be used as arunning board by applying paint thereto and then applying grit or thelike to the wet paint. In either case, it enables the ridge portion ofthe roof to be located close to the established tunnel clearance outlineand it also enables the portions of the roof between said longitudinalridge panel and the eaves to be located close to said clearance line. Atthe same time, the termination` of the depressed panels, at pointsoutwardly from Athe longitudinal ridge panel, is made feasible by theuse of the carline 'members with substantial decrease in the overallthickness or depth of the roof, particularly along the region of theridge and thereby increases the headroom and loading capacity of thecar. For this purpose, it is not necessary that the carline member shallextend to and rest upon the side plates, as the formation of the roofsheets into alternating ribs and channels enables them to take care ofwhatever load the carline members may pass to them. It is also notedthat the invention allows considerable variation in the design of thecarline members to adapt them to their location and to the stresses towhich they m11 be subject and which they will pass along either to theside plates or'tol the roof sheets.

It is noted that the work of welding the carline member to the bodyportion of the sheet may be done at the factory and the sheet with thecarline member welded thereto may be shipped as a preassembled unit.Such unit construction is not only economical, but facilitates the workof assembling the roof units into the complete roof.

What I claim is:

1. A car roof comprising side plates, roof sheets extending from sideplate to side plate and having their ridge portions substantially flatfor a width substantially equal to the horizontal top portion of theestablished tunnel clearance outline, said sheets having, at their sidemargins,

upstanding flanges that extend from the sides of the flat ridge portionto near the eaves, carline members located mostly below the sheets buthaving an upstanding portion between adjacent sheet flanges and withtheir tops substantially following said clearance outline and iiush withthe tops of said flanges, and welds along said outline uniting adjacentsheets together and to the intervening carline members.

2. A car roof comprising side plates, roof sheets extending from sideplate to side plate and having their ridge portions substantially flatand the portion between said ridge portion and each eaves brokenconformably to the established tunnel clearance outline, said sheetshaving, at their side margins, upstanding ilanges that extend from thesides of the flat ridge portion to near the eaves, carline members belowgaps between "adjacent sheets along said ridge portions and having anupstanding portion between adjacent sheet flanges with its topsubstantially flush with the tops of `said flanges, welds filling saidgaps and opposite said edges and uniting adjacent sheets together and tothe intervening carline members.

3. A car'roof comprising side plates, roof sheets extending from sideplate to side plate, carline members located mainly below the roofsheets with portions extending upwardly between the edges of adjacentsheets, and welds close to the established tunnel clearance outlineuniting adjacent sheets together and to the adjacent carline member, theridge portion of the sheets for a width substantially' equal to thehorizontal top portion of the established tunnel clearance outline beingsubstantially iiat and close to said outline and the portion betweensaid ridge portion and each eaves having breaks to conform such portionapproximately to the established tunnel clearance outline and having adepressed panel extending along the middle thereof cross- Awise of thecar.
